/* ===== auth.css — login / register / password-reset pages =====
   Consumers: accounts/login.html, accounts/register.html,

   Loaded after style.css via {% block extra_css %}.

   The shared form primitives (.field-group, .field-hint, .field-error,
   .auth-alert, .checkbox-row, and every bare input/label/select/textarea rule)
   stay in style.css — they are used by every form in the app, not just auth. */
